This gives a good account of the suit worn by Fred Haise which is, most likely, the one he is wearing in this shot.

Hard to believe that is the same suit, with the Duke name tag and no red stripes. What is the suit number?

On further investigation, the Apollo Lunar Surface Journal gives astronaut Haise two unique suit numbers - 324 for Primary and 305 for Training, neither of which had been used before. Likewise Mitchell with 325 and 321. Roosa has 401 and 085 which he recycled as back-up on Apollo 17 so the mystery deepens.

Maybe the crew needed to wear the prime crews suits for this photo opportunity which certainly looks staged. It's a shot I haven't seen before and a higher resolution version would obviously help. Anyone have one?

Those look like beta cloth mission patches to me.

The crew might very well be wearing the prime suits as you suggest. I don't recall ever seeing Apollo mission patches on the training suits of a backup crew.

Had Apollo 19 not been cancelled, I guess it would have been Haise, Pogue and Carr in the photo.

I don't seen any reason to suspect that embroidered patches were produced for any backup crews apart from Apollo 14. Or am I missing something?

The black and white Apollo 16 backup crew photos posted above might have been taken on April 11, 1972. Haise, Roosa and Mitchell were suited up at KSC for CM simulator EVA training on that day.

Photo 72-H-427 was taken the following day on April 12, 1972. Both the prime and backup LM crewmembers can be seen in the Flight Crew Training Building at KSC. Young does not have a beta cloth mission patch on his spacesuit, but he does appear to have the design of a four-leaf clover on his suit at waist level.

Looks like the Apollo 17 crew had beta cloth mission patches on their training suits also. I would say those were training suits because of the "E. CERNAN" name tag and the dirt on his sleeve.
